The region of the spectrum that best corresponds to light with a wavelength equal to;
1) The diameter of a hydrogen atom is; X-ray
2) The width of your pinky finger; microwaves.
3) The size of a virus; X-ray and Ultraviolet rays.
<h3>Electromagnetic spectrum</h3>
- From online tables, the diameter of an hydrogen atom is approximately 1 × 10^(-10) m but according to electromagnetic spectrum, any wavelength between 10^(-8) m and 10^(-12) m is an x-ray.
- From online tables, width of your pinky finger is 1.06 × 10^(-2) m but according to the electromagnetic spectrum the range between 1 and 10^(-3) m corresponds to microwave.
- The size of a virus has the range from 2 × 10^(-9) m to 4 × 10^(-7) m. This Range falls into x-ray or ultraviolet rays.
The complete question is;
What region of the spectrum best corresponds to light with a wavelength equal to:
(1) the diameter of a hydrogen atom
(2) the width of your pinky finger
(3) the size of a virus
Choices:
(A) radio
(B) mircowave
(C) infrared
(D) visible light
(E) gamma ray
(F) x-ray
(G) ultraviolet

It has been scientifically proven that laughter is excellent for emotional and physical well-being. The laugh can relieve physical tension, enhance the functioning of the immune system and decreases stress hormones.
It has been shown that laughter can relax facial muscles, which is fundamental for relieving physical tension.
Moreover, it has also been demonstrated that laughter can increase the heart rate and boost the adaptive immune system by generating antibodies that fight against harmful infectious agents (e.g. bacteria and viruses).
Finally, laughter can also decrease the levels of stress hormones such as cortisol, adrenaline and growth hormones.
